11.2.3.3 Break Function
The break function can be used to perform an
emergency shutdown of the application being driv-
en by the PWM signals.
The break function is activated by the external
BREAK pin or internal comparator output. This can
be selected by using the BRSEL bit in BREAKCR
Register. In order to use the break function it must
be previously enabled by software setting the
BPEN bit in the BREAKCR register.
The Break active level can be programmed by the
BREDGE bit in the BREAKCR register. When an
active level is detected on the BREAK pin, the BA
bit is set and the break function is activated. In this
case, the PWM signals are forced to BREAK value
if respective OEx bit is set in PWMCR register.
Software can set the BA bit to activate the break
function without using the BREAK pin. The BREN1
and BREN2 bits in the BREAKEN Register are
used to enable the break activation on the 2

break for PWM2 and PWM3 is enabled by the
BREN2 bit. In Single Timer Mode, the BREN1 bit
enables the break for all PWM channels.
When a break function is activated (BA bit =1 and
BREN1/BREN2 =1):
